Air Bearing

An air bearing is a type of bearing that uses a thin layer of air to support a load and reduce friction between two surfaces. The air can be supplied by a compressed air source or by a fan. Air bearings are commonly used in high-precision machinery such as coordinate measuring machines, semiconductor manufacturing equipment, and optical instruments. They offer several advantages over traditional mechanical bearings, including low friction, high accuracy, and minimal wear. However, they also require a constant supply of clean, dry air to maintain their performance.
